Tricking an antitheft?
Posted to Technical Discussion Forum on 1/17/2009 15 Replies

I have a 91 Deville with a bad antitheft module. It will not enable the starter or PCM. There is one wire to the PCM to enable the antitheft. Anyone know what signal/voltage/etc. should be on that wire? MOD does not tell me. Login to read more.
